Admixture and extrudable hydraulic composition |
(57) An admixture comprising a nonionic water-soluble cellulose ether having an average
particle size of 120-500 µm is suited for hydraulic compositions. The admixture does
not form clumps even in the presence of a large amount of water. The hydraulic composition
having a proper amount of the admixture added is effectively extrudable.
